Compiling meter code with CE code images

Posted: 28 Jan 2014     Print Version  Bookmark and Share

Keywords:electricity metering ICs  computation engine  Keil  compiler  Maxim 

The 71M6531/71M6532 and 71M6533/71M6534 and 71M6541/71M6542/71M6543 families of electricity metering ICs are designed to be used with computation engine (CE) codes that can be adapted to the application at hand. In some cases, special CE codes are required and supplied by Maxim to support different sensor types or features such as filtering or harmonic analysis.

Since CE codes occupy different spaces in flash memory and XRAM, depending on the application, several steps are needed to accommodate a specific CE code image. This is done by modifying both the meter code (demo code or meter application code) sources and the Keil compiler settings (KeilµVision 4).

This application note discusses the necessary steps to successfully integrate a new CE code image into meter code. A general knowledge of the tools, i.e. KeilµVision and Signum Systems WEMU51 is helpful when performing the tasks described in this application note. Reading the software user guide (SUG) for the 71M653x and/or 71M654x ICs is recommended.
